An x-ray study of a single crystal of the composition NBu4tMnCr(C204)3] reveals a layered structure with an ordered distribution of Mn2+ and Cr3+ ions. The ferromagentic system which arises here is a quasi-2D system in terms of the nature of its exchange interactions. According to data on the orientation dependence of the magnetization in an external field, the magnetic moments of Mn2+ and Cr3+ are directed along the с axis of the crystal.
